templates/csp_source_test.go scans .templ sources and fails the build on
the three authoring patterns hash-mode CSP refuses silently: native on*=
handler attributes (quote and templ brace forms), inline <script>
content outside the sanctioned theme_flash_guard.templ, and htmx's
eval-dependent bindings (hx-on*, js:-prefixed hx-vals — 'unsafe-eval' is
not granted). Verified to fire on all four violation classes via a
scratch probe file.
The dry run immediately caught a live leftover: unlinked_books.templ's
onchange="updateSelectedCount()" — CSP-refused since the hash flip.
Removed; the count already updates through the document-level delegated
change listener that x-init="setupEventDelegation()" registers.
AGENTS.md gains a "CSP discipline" ALWAYS-apply section documenting the
hash allow-list, the sanctioned-guard invariant, the replacement
patterns, and the tripwire test.
Verified: go build/vet, templates+middleware+docs tests green; /unlinked-
books loads with zero console violations (no fixture rows to exercise the
checkbox; the delegated path is unchanged code).
